Although scientists try to include what should be the 3 most common viruses in the Flumist (Influenza Vaccine), they can’t predict exactly which ones will be the worst during the flu season.

There's up to a 20% chance that you could still get the flu even after getting the Flumist (Influenza Vaccine).

It can take up to two weeks for the vaccine to kick in and protect you from the flu.

You'll need to get vaccinated every year to protect you from the flu.

How it works

The Flumist (Influenza Vaccine) is an inactivated vaccine (made from a dead virus) that protects you from the flu (influenza). The vaccine helps your immune system create antibodies, which are proteins that identify and destroy bacteria and viruses, including the influenza virus.
